VIOLA SAGITTATA SUBSAGITTATA (Greene). 
V. subsagittata Greene, Pitt. 3: 316-317. 1898 
Professor Greene thus explains his description: ‘‘I here pro- 
pose, for a new subspecies, what is known throughout a great 
extent of country west of Lake Michigan, as V. sagittata.” He 
further states that the differences consist in the marked pubes- 
cence, the larger flowers, and the smaller dimensions of the 
plant. I infer from his characterization of it as a subspecies 
that Dr. Greene would agree with my disposal of it as a geo- 
graphical variety. :

V. sagittata var. 8 emarginata Nutt. Gen. 148. 1818. 
It is unnecessary to add anything to the very elaborate 
description of this plant published, with figures, in Pittonia 3+ 
255, especially as Dr. Britton has also admitted the species in ; 
the Appendix to the third volume of the Mlustrated Flora, It 
should be observed that although Le Conte raised Nuttall’s 
variety to specific rank, and hence must be quoted as authority 
for the name, the plant which he had in mind, as shown by his 
figure and description was the following: 
VIOLA DENTATA Pursh, Fl. Am. Sept, ¥; 172. Lois: 
V. Porteriana Pollard, Bull. Torr. Club 24: 404. 1897. 
Misled by Le Conte’s reference of Pursh’s dentata to emar- 
ginata, | redescribed this imposing violet last year, after abun- 
dant specimens had been secured on an excursion of the Torrey 
Club to Bushkill, Pa. While its relationship is with V. ovata, 
I do not think the two plants can readily be mistaken for each 
other, and there is the further fact to be noted that dentata is 4 
species of high altitudinal distribution, all the material that I 
have examined having been collected either in the mountains of 
eastern Pennsylvania or the Blue ridge in Virginia.
